According to The Sun, further ground level CCTV footage then shows the group entering the Marche de la Madeleine via a backdoor before they made their way to a nearby carpark and escaped on local hire bicycles.

Police have seized cigarette butts from outside the carpark that they believe may have been smoked by the criminals.

Breaking into Kardashian West's home in the early hours of Monday morning, the five masked men dressed as police handcuffed up the building's concierge and demanded he let them into the star's apartment before holding the mother-of-two at gunpoint, restraining her and combing the apartment for her collection of fine jewels.

TMZ is reporting that police consider the concierge to be a critical witness in the investigation.

According to the site, the 35-year-old reality star told Paris cops by phone the concierge was handcuffed when he opened the door to her apartment and remained “extremely calm” during the harrowing ordeal.

“He opened the door and led them [the robbers] up and was in there the whole time,” Kardashian West allegedly told police during an interview, adding that despite being cuffed, the concierge remained "extremely calm" throughout the ordeal.

The robbery was over in just six minutes, with many now believing it must have been an inside job due to the group's accuracy.

And as the days go on, Kardashian West is said to now be blaming herself for the robbery.

“Kim’s in shock and blaming herself. She’s tearing herself up that she Snapchatted the ring so much and wore it all the time,” a source purportedly close to the family told People magazine. “This incident is making her question everything. How she dresses, what she does.”

“Kanye wants to buy her the [engagement] ring again but she just says she doesn’t want to think about it. He says he wants everything to go back to normal and for the incident to not affect their lives,” the family friend told People.

Sisters Kim, Kourtney, Khloe, Kendall and mother Kris are all yet to post on social media since the harrowing event.
